1/ The world is facing a 'ticking time bomb' from its supply of oil, according to a briefing note from JP Morgan. Physical scarcity of oil is about to unfold across the globe, spreading sequentially through April from east to west, causing major economic disruption worldwide. ⬇️
2/ The blocking of the Strait of Hormuz has reduced traffic through the strait by 97%, cutting off most of the Persian Gulf oil and gas supply from tanker shipment. The reduction in the supply of oil is twice as large as seen in any previous oil crisis, according to the IEA.
3/ This has not yet resulted in physical shortages of oil – although shortages have already been seen, for instance in Australia, this has been due to excessive demand caused by panic buying rather than an interruption in supply. That is about to change.
4/ J.P. Morgan Commodities Research / Kpler has charted the global distribution of seaborne crude oil exports from the Persian Gulf to global trading hubs, with approximate delivery cutoff dates annotated by region to reflect the arrival of the last Gulf shipments.
5/ Asia dominates as the primary destination for Persian Gulf crude. The three largest single recipients are:
🔺 China — 5.2 millions of barrels per day (mbd), by far the largest importer
🔺 Japan — 2.3 mbd
🔺 South Korea — 2.2 mbd
🔺 India — 2.3 mbd
6/ Together, these four nations absorb the vast majority of Persian Gulf output, reflecting Asia's structural dependence on Middle Eastern oil to fuel its industrial economies. China and India in particular are now far bigger consumers than in previous oil crises.
7/ European destinations are numerous but individually modest. The continent receives oil through several routes, with the Netherlands (0.30 mbd), France (0.25 mbd), UK (0.16 mbd), and Italy (0.13 mbd) as the leading recipients.
8/ Collectively, European imports are significant, but no single country approaches the volumes seen in Northeast Asia.
9/ The United States receives a comparatively small 0.65 mbd, reflecting its increased domestic production since the shale revolution.
10/ Australia (0.95 mbd) stands out as a substantial recipient for a mid-sized economy, reflecting its limited domestic refining capacity and geographic proximity to Asian supply chains. The lack of domestic refining capacity is already emerging there as a political flashpoint.
11/ While the Persian Gulf is not the only supplier of crude, the oil supply routes emerging from it are by far the most numerous and wide-ranging, reflecting the Gulf's position as the world's primary crude oil supplier.
12/ The non-Persian Gulf flows in Asia — from Singapore, South Korea, Malaysia, and India — are shorter-haul and concentrated within the Indo-Pacific, reflecting regional refining and re-export activity.
13/ Most deliveries from the Gulf are in the process of stopping between now and April 20th. Regions closest to the Gulf are feeling the impact first, with Europe, the US and the Pacific last due to the longer shipping distances:
14/ 🔺 Southern Africa / Indian Ocean — March 20th–April 1st (earliest)
🔺 East Asia — April 1st (China, Japan, Korea cluster)
🔺 Europe — April 10th
🔺 United States — April 15th (latest)
🔺 Australia/Pacific — April 20th (latest)
15/ After these dates, the Gulf oil currently at sea runs out, and the next wave of deliveries will arrive later, costlier, and in smaller volumes from different producers.
16/ This will have the biggest impact on China. At 5.2 mbd, any disruption to Persian Gulf supply would hit China harder than any other nation, with limited short-term substitution options. Approximately a third of China's oil supply comes from the Gulf.
17/ Europe has more supply diversity than Asia, given its access to North African, West African, American, and North Sea alternatives, explaining its relatively lower per-country import volumes.
18/ In contrast to the rest, the US is largely insulated from Persian Gulf supply shocks compared to Asian peers, though it remains exposed through global price mechanisms – in other words, higher costs elsewhere will be reflected in the cost of imports to the US.
19/ As JP Morgan's briefing note says:
"Much like during COVID, the shock unfolds sequentially rather than simultaneously—a rolling supply disruption moving westward, dictated by shipping times and buffered unevenly by regional inventories."
20/ "This means Asia—heavily reliant on Gulf crude and products—is already feeling the squeeze as pre-closure cargoes have largely dried up.
21/ "In April, Southeast Asia’s demand is expected to fall by about 300 kbd, but losses could climb rapidly—surpassing 2 mbd in May and approaching 3 mbd by June—if OECD stock releases remain contained within their respective countries.
22/ "Africa is next, with effects becoming more pronounced in early April, though outcomes will vary widely depending on local stock levels and import dependency. Up to 250 kbd of demand losses are possible in April if inland stocks are low.
23/ "Europe is likely to feel the impact by mid-April, as the last February loadings arrive without replacement, but the shock is shaped more by rising costs and competition with Asia than by outright shortages...
24/ "The US is last in line. With longer voyage times and substantial domestic production, direct physical shortages are unlikely in the near term.
25/ "Instead, the impact will be felt mainly through higher prices and dislocations in refined product markets—especially in California—rather than outright scarcity." /end

1/ Russian warbloggers warn of an alarming development: Ukraine's long-range drone strikes into Russia are reportedly being guided by Starlink connections, which potentially provides drones with precise and unjammable navigation across the entire country. ⬇️
2/ While Starlink is normally a civilian network, Ukraine makes extensive use of it for military purposes, including on the front lines and in sea drones. Until recently, Starlink was blocked in Russia but not in Ukraine, which enabled the Russian military to use it as well.
3/ This changed in February 2026 when Starlink began whitelisting terminals in Ukraine, so that only the Ukrainians could use it. Ukraine also has access to a limited number (reportedly 3,000) of terminals which can access the separate military-oriented Starshield network.
1/ Russia has reportedly provided Iran with targeting data on Israel's critical energy infrastructure, according to Ukrainian intelligence sources quoted by the Jerusalem Post. ⬇️
1/ Russia's blocking of Telegram is having a devastating effect on the volunteer communities that support the Russian army in Ukraine. A Russian warblogger posts a despairing account of how the 'humanitarian aid' system has all but collapsed as a result. ⬇️
2/ The Russian army is hugely dependent on volunteer-provided 'humanitarian aid' – which in practice means anything from drones to generators to bulletproof vests – because so little is provided by the Russian Ministry of Defence. Alexander Zaborovsky writes:
3/ "I’m talking about Telegram blocks and specifically what has been drastically affected by them.
I’m referring to volunteer organisations and groups. 99% of them rely on Telegram for communication, including with combat units.
1/ Goldman Sachs analysts report that the biggest oil crisis in history is about to hit globally, with profound and highly destructive consequences. A new report asks ""Are We Running Out of Oil?", and concludes that the answer is yes. ⬇️
2/ Goldman reports that average daily flows of shipping through the Strait of Hormuz have fallen by 94% from their pre-war levels.
3/ This has led to a 63% collapse in the flow of oil and its refined products from the Middle East. Exports are down from 7.4 million to 2.8 million barrels per day of oil, 39% of which is flowing via a pipeline to Saudi Arabia's Red Sea ports.
1/ A shortage of drones reportedly means that Russian drone pilots often don't attack Ukrainian vehicles again after disabling them. This, says a serving Russian soldier, means that the Ukrainians are frequently able to retrieve disabled vehicles. ⬇️
2/ Russian forces in Ukraine have been complaining for a long time that they lack drones, with those provided by the Russian MOD being few and often of poor quality.
3/ Instead, they often have to rely on voluntary donations and unofficial drone production by the so-called 'people's military-industrial complex' – an ecosystem of enthusiasts and ex-military personnel who make or import drones for military use.
1/ News of the destruction of yet another US aircraft on the ground is being met with incredulity by Russian Air Force pilots. They ask if the United States has learned nothing from Russia's own very costly experiences. ⬇️
2/ 'The Voivode Broadcasts', a Telegram channel run by a group of Russian military helicopter pilots, expresses astonishment at pictures published overnight of a US CH-47 Chinook helicopter that was destroyed on the ground in Kuwait.
3/ "I look at this photo and realize that the Americans, with all their budgets and all, haven't studied or systematized our experience in any way.
